Add catppuccin colorscheme

[ceuk]

I thought I'd see if you wanted to merge the colorscheme I wrote based around the highly popular Catppuccin color palette.

I think it looks pretty nice, and could make for a nice option for people in addition to the current defaults.

that is very cool

whoa thats pretty insane, im going to have to update my catppuccin theme, also can you somehow make changing font easier, like use some kind of variable that would change all font family occurences?

[ceuk]

These changes all make sense, I have around an hour now so will try get them all done, if not I'll try finish them off soon

[ceuk]

Hey @Jelmerro I think that's everything if you want to have another look :+1:

[ceuk]

I'll try sort the above later :+1:
